Application filed January 22,1918. Serial No. 213,245.

To all whom it may concern:

Be it known that I, ANDREW EBEnsoLn, a citizen; of the Unite'd 2 States,residing at Dodge City, in the county-of Ford and State of Kansas, haveinvented a new=and useful Portable Transferring-Derrick, of which the-fOll0W1Ilg-1S 2t SPGQlfiOZttlOIl.

My invention relates to portable -transferring derricks, which areemployed to hoistyconvey and transfer farm products from point to point,as froma reapingmachine to astack', The objects of my invention are toprovide a cheap, durable and portable transferring derrick for farm'use.

I attain these and other objects by means of the mechanism illustrated"in the accompanying drawing in whichFigur e 1, is a side elevation ofthe derrick, partly {sec it tioned to disclose the method of pivotingthe mast; Fig. 2, is a top plan view of the derrick, the mast beingshown in cross section at the supporting platform, and showing the cablerunway channel and the ring which holds the cable in the channel; Fig.

3, is a top plan view of the rigid arm, and

showing the inner end thereof straddling the mast; Fig. 4, is a verticalelevation of the mast, and showing the cable runway channel in its side,and Fig. 5, is an end elevation of the derrick, and showing the hoistattached to the mast, the upper platform being broken away to disclosethe cable runway channel and the position of the detaining ring, therigid arm and hoisting rigging being omitted.

Similar numerals of reference refer to corresponding parts throughoutthe several views.

The runners 1, cross ties 2, cross rods 3, cross-tree 4, and anchor eyes5, constitute the sled or drag for transporting the organized mechanismfrom place to place about a farm. A platform 6, is secured on the crossties 2, and spaced apart from the inner sides of the runners 1, a littledistance. The platform is of a thickness best adapted to have formedcentrally therein a substantial pivot bearing 7, provided with asupporting shoulder 8. Inwardly and upwardly extending inclinedstandards 9, are fixed at their lower ends to the corners of theplatform 6, their upper ends being connected by cross ties 10. Thepreferable height of the posts is a distance in excess of the middle ofa mast hereinafter described. A platform 11, having a central opening12, is secured on the upper ends of the standards. A vert1ca'lly'-extend-mg revolubly mounted mast 13, havinga pivot 14, entered in thepivot *bearmg 7, and a shoulder 15, bearing on the shoulder 8;, isextended upwardly through "the opening in the platform '11, andthereabove a suitable distance. The mast is, preferably, made of acircular timber of maxi- 1 mum strength and minimum weight An inwardlycurved channel 16, is' formed longitudinally in themast, so that thechannel 51151 11 extenda distance above and below the platform 11,f0r=apurpose that will hereinafter' be explained; A metal ring 17, isdemountab-ly secured on the mastfin such a manner that itwill traversethe channel '16, and enter the opening 12, in the platform 11, and bearon" the vertical face of theopening andslide thereon in the revolving ofthe mast. An outwardly extending upwardly inclined arm 18, is fixed atits inner end to the mast by bolts 19, which pierce the arm andpenetrate the mast, or any other fastening means. A brace 20, is rigidlyconnected between the mast and arm to provide added strength and supportto assure the integrity of the arm. The arm 18, is formed of a pair ofside members 21 and 22, which are, preferably made of suitable timbershaving their outer ends united and their inner end portions spaced apartand respectively fixed to opposite sides of the mast. Cross ties 23, areconnected between the side members at points adapted to lend rigidity tothe arm. A pulley 24, is mounted on the under side of the outer endportion of the arm, and a similar pulley 25, is mounted on the mastbelow and adjacent the arm. A hoist 26, is mounted on the lower portionof the mast at a point best adapted for manual operation. The hoistcomprises a frame 27, which is attached to the mast, a revoluble shaft28, provided with a drum 29, and a gear wheel 30,'the latter beingengaged by a pinion 31, on a revoluble shaft 32, having a crank 33. Acable 34, is attached. to the drum 29, and is extended upwardly into andthrough the channel 16, behind the ring 17, and over the pulley 25, andpulley 24, and thence to earth. A hook 35, is secured on the outer endof the cable, and a similar hook 86, is loosely mounted on the cable, sothat it may slide thereon and be adjusted to and from the firstmentioned hook. A flexible barge covering 87, is detachably mounted on.said hooks, and is adapted to receive a load of arge, wagon, or othervehicle, or upon the ground, and is then loaded. When loaded, the hook35, is attached to one end of the covering and the free hook 36, isattached to its opposite end. The hoist is then operated to lift theload, the gravity of which resists to the utmost the pull of the hoist,thereby the hook 36, is forced to slide toward the hook 35, and thecovering is drawn together over its load and the mass lifted. lVhen themass is free, the mast is revolved by a pushing or pulling pressureapplied to the hoist frame, thus the load is transferred to the stack orother selected point and discharged by detaching the hook 36. The cable34, being detained in thechannel 16, in the mast, is carried by thelatter within its bearing in the platform 11, and without interferencewith the mast support. The

simplicity of the derrick, combined with a hoist adapted for exertinggreat leverage, provides a cheap, useful and eflicient farm derrickwhich may be operated by youthful ,members of the family when labor isscarce.

Having described my invention what I claim is l V In a portabletransferring derrick, the combination with the mainframe and the mastpivoting on the lower portion of the frame and having a cable runway inits side, of a plate disposed horizontally on the upper end of theframeand having an opening for loosely receiving the mast, and-a ringdemountably arranged on the mast over the cable runway therein andjournaled in said plate.
